To allaohom it may concern: -Be it known that I JDNAB Non'rnnor, a citizen of the United States residing at Hopedele in the county of- Worcester. end Massachusetts, have invented con tain new and useful Improvements in Thread Parting and Clumpin Mechanism; and I do hereby declare the f llowing to be a full, clear, and exact description of the invention, such as will enable others skilled .in the art to which it,eppertains to make and use the some:

The present inventionrelates to an provement in threed arting and clamping mechanisms for weitareplemshing looms.

' In filling f'eele'r controlled, weft replenishing looms, wherein the weft replenishing mechanism is located on one si e of the looin and the filling feels! mechanism is located-on the opposite side of the loo the filling detector mechanism for Tleteotm the presence orabsence of filling iivthe shed is usually located at the filling footer side of the loom. This srra emeiit is not satiscompletely unwinds mm the bobbin wln e the shuttle is travelingtoword the replenishing side of theloo'm after the indication of critical, oxheustion of the filling, u mispiok will result.

detector is lo'catedon the replenishing side'of the loom, the absence of the filling caused by its com lete exhaustion from, the bobbin will be loom stop d so that the short weft can be removed the operator. ZBut, when the filling fork-of the detectoi: mechanism is located beside the replenishing. mechanism the ebsencepr presence of 6 'ng in the shed for the first few beets nfte 'replemshment so cannot alw'a s be detected because of the .pre'sence'of the outgoinf or incommgfilling ds, It is ucoor ing y proposed in the g reseut invention to produce an im toyed thread porting and clamping mec an sm having provision for drawing the outgoing ma incoming filling ends toward the breast beam into such position that the will be out of the range of action of a. ding fork located at the replenishing side of the loom. By the provision of this improved thread arting and clumping mechanism the filling detector mechanism me be located and successfully operated on t c replenlshing side of the loom; i The thread parting and clamping mechapointed out in the up positions assumed by the tected. and the beam and extends connected on the loiver -end nism of the resent invention is particularly dad 0111308, and the preferred specific em odiment of the invention is described in the following specifier tion and is illustrated in the accompanying e0 drawings, in which Figure 1 is a. plan-view of a part of the replenishing end of s weft replenishm loom, showing'the application thereto of t e improved thread parting and clamping mechanism and its position rein-"6s txvely to the loom-temple-end the filling de-' teeter mechanism; Fig. 2'is, a. side elevation of the thread part and clamping mocha msm, with the associated parts ofthe l m necessary for its operation; Fig. 8 is, a.

which the replenishing mechanism is located at one side 0 the loom and the filli feeler mechanism at the opposite side. Bot these mechanisms ma be of any usu'al or preferred construction. The weft replenishing mechanism is in art indicated by the hop- 90. per platelO, whi l is sup rted on a bucket 11 secured to the breast em 12. The releuishi mechanism is connected with the ling fe er mechanism (not shown in the drawings) by e-rock or change shaft 14 which is mounted on the front of the breast transversely thereof. A hopper arm 15 is secured to the change she and is dvieldingly connected with an arm 16 exten ing upwardly from a hub 17 loosely mounted on a stu 1B fastened in the hopper plate 10. The chat shaft 14 and'its associated parts, by which the replen'ish' goperetion is initiated, are known as the horn controlli devices, De nding 105 downwardly from th fiiub 17 is'a. l lifting arm 20 having a slot at its lower end ada ted to receive a pin 21 projecting lotare y from the latch 22; wh oh la plvotallof an arm; an

extending downwardly from the hub 26 The shuttle feeler 29, in a clamping m mechanism is indicated of the transferrer hammer 27, of which only a portion is shown in the drawings. When the filling feeler mechanism indicates predetermined exhaustion of the filling, the change shaft 14 is oscillated in a direction to swing the hopper arm 1Q outwardly, that is, to the right, viewing Fig. 2, thereby acting on the arm 20 to present the latch 22 in the path of the hunter 28 secured to the front, of the lay 24. vTheindicution oi redetemnined exhaustion of fillin takes 1) ace on one beat-up of the lay, an the replenishing operation takes place on the succeeding beat-up of the lay. Coiiperating with these parts is a, shuttle feeler 29 pivoted on a stu 80 secured in the hog 1 plate 10.

ition to its usual shuttle feeling function, constitutes a part of the thread parting and clam the latter purpose its connection with the loom wntrolling devices is novel with the resent invention. It performs its shuttle eeli function, however, in the usual manner, t at is to say, when the filling feeler mechanism indicates predetermined exhaustion of filling and thereby o crates to swing the hopper arm 15 outw'a ly the shuttle feoler is thrown into shuttle ieeling position, so that, if on the next succeeding or replenishing beatup of the la;' the shuttle 31 is improperly boxed, it will strike the lower end of the shuttle feeler and push it toward the breast beam, to drop thelatch 22 out of the at of the hunter 28. The manner in whic this function is performed will be more fully .described in the articular description of the construction 0 the thread parting and The filling detector mechanism for determining the resence or abmnce of filling in the shed is coated at the replenishing side of the loom between the replonishi mechanism and the cloth selvage. The ete'otor nor-ally by the ref erence character 33, an computes a filling for]: 34 pivoted un the rear end of a de tector sliders, the forward end of which.

engages an arm 36 secured to and extending upwardly from a hollow stop shaft 37 connectcd at the other end of the loom with the loom stopping devices. The detector slide 35 is loosely supported in a guidevmf 88 fastened to the breast boom 12. The fil inglfork 34 is provided with a tail or ball 39 which, when filling is absent and the fork is not tilted,,co6perates witha hook 40 of the. weft hammer 41 to 'vetlie slide 36 a forward movement" to osc ate the arm 36 and the stop shaft 37 to stoptheloom. For the purposes of the present invention the tines of the filling fork 34 are located between ,the' fork pivot 43 and the breast mechanism of the present invention, an for thereby o erating' beam so that the forlrwill have an immediate' rising action when the tines are pressed by a fill end on their rear side. loom tom e is indicated at 45 and'is provided wit a thread cutter which operates to art the outioi and incoming fillng an s at the clot a yoga. The foregoin parts, with the exception of the shuttle fee or, are all constructed and operate in a manner familiar to thoseskilled in the art. The improved thread parting and clampmg mechanism operates first to m clamp the outgoing filling end an hold it in a osit lon out of the range of action of the fi ling fork, and then to clampb'ut-not sever the incoming filling end and hold it also out of the range of action of the filling fork. The parting and clamtping of the out going filli end occurs on ie replenishing eat-up of e lay, and the clamtging of the incoming filling end occurs on e succeeding beat-up of the lay. During each operation, the resipective filling ends are on god and drawn orward toward the breast ain,

'and in so doing they first come into en ment with the tines of the filling fork which is so constructed that the filling easily tilts the fork and asses by the tines, permitting the filling for to return immediately into filling detecting. osition. As a result of this operation the notion of the filling fork in detectin the absence or presence of the filling in t e shed is not interfered with by either the outgoing or the incoming filli ends. The incomin filling end is permittei. to be drawn forwa toward the breast beam without liabili of breakage because the act of pulling is toward the breast beamfis performe is be' picked from the re wish of the o h immediate] f0 owing plenishinmoperetion an of the warp threads for the next shedding.

before the closing end is performed by a thread The and

ilsoapss upper end of the hopper arm 15. Depending from the cross-bar of the T-shaped P1806 57 is a leg 60 having a projectmg p n 62 which normally engages the rear side of the upward] extendin part 63 of the movable blades. V outward] on the indication of predetermined ex austion of the fillin it carries the T-shaped piece 57 with it, t ereb forcin the )in 62 against the movable b ades an oscillating them on the pin 53 into open position, as shown in Fig. 3. The thread parting and clamping means is now in po tion to receive the outgoing fillin end, It ill be observed b reference to Figs. 1' and 2 that the three parting and clampin means is beyond the limit of the forwar movement of the lay," and that, therefore, the outgoing fillin end must be drawn between the arting an clam ing blades. The shuttle eeler performs tliis function, the lower end thereof being constructed and arran ed to act as a thread book. The shuttle fee er is connected with the forward end of the T-piece 57 by means of a spring 65 fastened to the piece 57, and a strap 66 fastened to the hub of the shuttle feeler. The shuttle feeler is held in its normal position, 'as shown in Figs. 1 and 2, bya cam .piece 68 pivotally mounted on a pin 69 passed through the upper end of thearm 16. The forward end of the cam piece 68 is provided with an upward extension 70, the up er end of which is connected by a spring 71 with the bracket 59 fastened on the hopper arm 15. The cam iece 68 is provided with two recesses 72 and 73 which are adapted to receive a in 74 projecting laterally from the shuttle eeler. When the shuttle feeler is in normal position, the pin 74 is received in the recess 72, as shown in Ft 2, and when the shuttle 'feeler is in shut't e feeling position, or is in position preliminary to engaging the -incoming filling end, the pin 7* is received in the recess 73. The cam piece 68 is provided with a surface 75 which is adapted, when the hopper arm 15 moves outwardly, to come into contact with the hub 17: While the cam piece 68 is in this position, with theshuttle feeler in shuttle feeling position, and a shuttle is improperly boxe on the replenishing -beat-up of the lay and therefore strikes the lower end of the shuttle feeler, the pressure of the shuttle feeler against the rear end of the cam iece 68 serves to oscillate the arm 16 and the parts connected with it about. the stud 19 as a fulcrhm to depress the latch 22 out of the path of the hunter 28. It is thus seen that the shuttle feeler performs its usual function in preventing the weft replenishing operation, in the event of an improperly boxed shuttle on thereplenishing beat-up of the iVhen the shuttle feeler has been thrown 'eration of the. loom controllin so that, as the lay moves forwar hen the 0p er arm 15 is moved.

7 end that is, if it is the strand of into its shuttle feeling position onan opdevices, as shown in Fig. 3 it is in the at of a bunter 76' secured to the top shutt e box on the succeeding beat-up the bunter 76 strikes the shuttle feeler and forces it forward. It will be observed that the lower end of the shuttle feeler being constructed and arranged to act as a thread hook, as the shuttle feeler is forced forward by the bunter 76 it enages the strand of filling extendin from t e selvage to the replenishing mec anism and draws it toward the breast beam. If this strand of filling is the-outgoing filling fil ing extending from the selvage to the bobbin about to be ejected fr'omthe shuttle, the fillin is drawn between the openparting an clamping jaws. Then, as the shuttle feeler continues lts forward movement under pres sure of the hunter 76, the part 78 on the lower end of the feeler presses on the surface 79 of the movable thread parting and clamping members and closes these members upon the filling, thereby severing the filling by the action of the blade 51 on the blade 50 and clamping the severed filling end by the action of the blade 52 on the o posite side of the blade 50. -It will be 0 served in this connection that the movable parting blade 51 is on the side of the blade 50 away from the selvage, and that .the clamping blade 52 is between the blade 50 and the selvage so as to hold the piece of filling extending from the selvage to the clamping means. As the outgoing filling end is bein drawn toward the breast beam by the sh tlefeeler, it first encounters the tines of he filing fork, and inasmuch as these tin are positioned with respect to the fork "vot 43 as described, the filling is easily dr wn past the tines in tilting them, thus permitting them to return immediately into t eir operative position. After the outgoing filling end has been parted and clamped by the parting and clamping means, it is held in the position with respect to the filling fork, as shown in Fig. 1, in which the reference character 80 indicates the out oin filling end; The outgoing filling on wil be held in this position until it is severed at the selvage by the temple thread cutter 46.

After the shuttle feeler'has been moved forward by the hunter 76 on the replenishing beat-up to deliver the outgoing filling end to the parting and clamping means, it agaih moves rearwarclly so as to be in position to engage the incoming filling end and draw it forward on the succeeding beat-.up

of the la The shuttle feeler is moved rear:

late 77,

on the replenishing beat-up by the hunter filling 76, the pin 74 was forced out of the recess 73 and traveled up along the surface 81 of the cam piece. This movement of the pin 74 relatively to the cam piece 68 of course 05- :cillated the partsconnected with the arm 16 about the stud 19 as a center, but inasmuch as at this time the hunter 28 had already engaged the latch 22, this movement of the parts connected with the arm 16 about the stud 19 had no operative eflect. These parts are so constructed as to provide for this relative inoperative movement. As the lay beats backward after the replenishing op eration, the hopper arm, as usual, moves rearwardly to its normal (position, thereby returning the arm 16 an the parts connected w1th it to their normal position. But inasmuch as the pin 74 at this time is on the rear side of the point 82 on the cam piece 68, the spring 71 operates to force the rear end of the cam piece 68 upwardly and the shuttle feeler rearwurdly. This movement is assisted by the action of the spring 65. The pin 74 is thereby again received in the recess 73, and so the shuttle feeler is held in rearward position. hen the lay has reached the limit of its rearward movement and the hopper arm 15 has returned to its normal position, the parts of the thread parting and clampin mechanism are in the ositions shown in Fig. 4. With the shuttle i eeler in the position shown in this figure, its shuttle feeling end is above the path of motion of the shuttle, when the shuttle is boxed at this end of the loom and the lay moves forward; consequently, it does not perform its shuttle feelm function on this beat-up, nor is this required; It is, however, in such position that as the lay moves forward on the beat-up following the replenishing operation, the hunter 76 will strike it and move it toward the breast beam. Durin this forward movement, its lower end will engage the inco ing filling end and pull it toward the breas beam. No provision'is made for severing the incoming fillin end, except at the "selvage by the temp e thread cutter 46-.- The inenming filling end isthereafter held in the position shown in Fig. 1, (in which the incoming filling end is indicated by the reference character 85) by the shuttle feeler which is now; in its normal position with the pin 74 in the rece s 72, having been forced almost to that posltion by the hunter 76. The ac tion of the cam piece 68 under the influence of the s ring 71 completes the reception of the pin 4 in the recess 72, so as to move the shuttle feeler toward the breast beam a slight distance beyond the limit of the forward movement of the hunter 76. As an aid in assisting the thread hook functions of the shuttle feeler, the lower end thereof is provided with a piece of felt 86, which prevents and consequent breaking of the also assists in holding the incoming filling end firmly until it is severed at the salvage. In order that the incoming filling end ma be drawn out of the replenishin shuttle ox, the front wall 87 thereof is 510 ted at 88. ,The incoming fillin end tilts and asses under the tines of the lling fork in t e same manner in which the outing filling end tilts and passes underthe lling fork tines. It will be recognized that while the shuttle feeler is drawin forward the incoming filling end, the shutt e is travcling through the shed paying out the filling. There is therefore no liabilit of breaking the incoming filling end in rawinght toward the breast beam.

he mode of operation of the improved thread parting and clamping mechanism will be briefly recapitulated': During the weaving operations of the loom the parts of the thread parting and clumping mechanism. are in the positions shown in Figs'] and 2. It is assumed that there has been .an indicw tion of predetermined exhaustion of filling in the active shuttle and that, as usual, throu h the 0 )eration of the loom controlling Eevices t e change shaft 14 has been oscillated to swing the hopper arm 15 outwardly. The outward movement of the hopper arm pulls the T-piece b7 forward, thereby opening the thread partin and clamping jaws and swinging the s uttle feeler into shuttle feeling position. While these movements are taking place, the shuttle has been picked to the replenishing end of the loom and the lay begins its replenishing beat-up. The flight of the shuttle to the replenishing side of the loom left the outgoing'filling end extending from the salvage to the weft replenishing mechanism, so that, as the lay now beats u) and the hunter 76 strikes the shuttle i eeler and pushes it forward toward the breast beam, the outgoing filling end is en aged by the shuttle feeler and delivered etween the open jaws of the parting and clamping blades. Almost simultaneously the'rewith,'the mov able blades are closed upon the filling, which is then parted and clamped as shown in Fig. 1, by the pressure of the shuttle feeler against the movable blades. During this beat-up of the lay the replenishin operation has taken place, as usual, an on the the chafin succeeding backward beat of the lay the spring 65 and the cam piece 68 in coijperation move the shuttle feeler into the position shown in Fig. 4. By the time the shuttle feeler has reached this position, which is its position preliminary to engagin the incoming filling end, the shuttle has een picked awe from the replenishing mechanism leaving the incoming filling end extending from the hopper stud 89 to the cloth selvage and the lay then beats up again. On this tle fee er and forces it orwardinto its normal position,

it is eld by the where it is held by the cam piece 68. During this beat-up of the lay,

-the shuttle feeler has drawn the incoming fillin end toward the breast beam, where shuttle feeler, as shown in the position m Fig. 1. Both the outgoing and incomin filling ends are thus in a position out o the range of action of the filling fork.

The thread parting and clamping mechanism, of the present invention has been shown and described as applied to a filling feeler controlled, weft replenishing loom. It will be understood that the invention is not limited to application to feeler looms, but that it may be applied to filling detector controlled, weft rep enishing looms. When the mechanism is applied to this latter type of loom, it is obvious that the thread parting and clamping blades. may be removed, because there is no outgoing fillin end to part and clamp. The incoming filing end, however, would be operated upon in exactl the same way as above described. It wil furthermore be recognized that the invention may be embodied in other forms than that shown and described, and yet be within the scope of the following claims.
